Compared to the previous version 0.5.1 there are a number of changes in this build, with the most significant ones being:

New features:

– new display configuration options for setting scale factor (1x and 2x, retaining a proper aspect ratio), and scaling strategy (solid/scanline); inclusion of higher screen resolutions to allow use of 2x windowed modes– support for 2x mode in Amiga Forever– support for model presets to quickly get started setting up model specific configurations (a number of presets already included)– support for creation of empty and formatted ADF images– automatic interlace compensation (WinFellow will automatically detect interlaced graphics and perform interlace compensation; this can be disabled in various options, but is on by default for new configurations)– lower system requirements (an SSE capable processor is no longer required)– Windows 8.1 added to the supported operating systems

Bug fixes:

– re-initialize the emulation session when a change of display adapter properties (color depth, different graphics adapter) is detected– cancelling the configuration dialog no longer performs changes to the configuration– support for sprites in hires dual playfield mode was fixed, making previously invisible objects visible on the screen– sprite DMA was being disabled instead of waiting, causing invisible sprites– PC -2 saved on the stack for address exception– proper "short frame" when display is interlaced and frame is short– fix copper list load– failure to find valid screen mode for screens with unusual refresh rates (Microsoft VirtualPC, ...)– fixes for several crashes to desktop caused by NULL pointer exceptions– cancelling an undo dialog in Amiga Forever will no longer close the emulation session– reset of Amiga Forever emulation session no longer causes input devices to no longer function– fixed problem with Amiga Forever clipping calculations for left offsets <16 (would lead to only half the screen being visible) or one of the offset values = 0 (would ignore the offsets completely)

Please see the included file ChangeLog.txt for a full list of changes.

Running much faster than current stable release of WinUae. Tried few games (my favourities) and there weren't any noticeable issues. Display settings are a spartan one, I don't have idea where I could put 2x mode, probably only in hi hi resolution. Scanlines mode in 640x480 looks like shit. In 640x480 the display is correctly placed, I don't remember if that works in old winfellow releases. F15-2 Strike Eagle has frozen few times (on loading screen). I was sceptical of rewriting asm code to C but i see that it works. But it still lacks many features, for example how to remap standard winfellow keys?
